Which is the median of 12, 32, 9, 11, 18, 20 and 28 *
Answers
Answer:
The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30. The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. Step 3: If there is an odd number of numbers, this middle number is the median. If there is an even number of numbers add the two middles and divide by 2.
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
12+32+9+11+18+20+28=130÷7
12+32+9+11+18+20+28=130÷7130÷7=18.5714286
12+32+9+11+18+20+28=130÷7130÷7=18.5714286please mark me as brainlist.......
